We have completed 4,000 hour weatherometer (WOM) testing of your Nano-Clear. It was compared to
PPG’s CeramiClear product and an OEM clearcoat from DuPont. In all categories tested, the NanoClear product performed better than or equivalent to the PPG and DuPont products. Nano-Clear
performed exceptionally well after 4,000 hours of WOM exposure. Refer to Table 3 for detailed test
results.
Table 1 details the clearcoats that were tested along with their physical properties. All tests were
performed on the Nano-Clear and PPG clearcoats (A & B) and some additional tests were performed on
the DuPont OEM clearcoat (C).

Clearcoats A and B were mixed according to their directions and applied to coated steel panels, within
15 minutes of mixing, using wire wound applicator method. They were allowed to flash off for 3 – 5
minutes prior to baking for 30 minutes at 150oF. They were aged for 24 hours under ambient conditions
prior to testing. Total clearcoat thickness for both clearcoats was 1.9 – 2.1 mils. Table 2 details the test
panels that were prepared.

Panels were tested for appearance, mechanical and durability properties similar to those required of
BMW. Descriptions of test methods can be found at the end of this report.
The Nano-Clear showed superior cold temperature chip resistance, direct and reverse impact resistance
compared to the CermiClear and OEM clearcoats. It showed slightly more haze than the CermiClear
product. Both Nano-Clear and CeramiClear showed no breakthrough of clearcoat after exposure to 100
liters of sand via the Falling Sand Abrasion Test. The OEM clearcoat failed after 100 liters.
The initial 20o gloss of the OEM clearcoat was slightly higher than the other clearcoats, but the NanoClear (A) showed the best gloss retention (100%) after 4,000 hours of WOM exposure. It had similar
color change than the DuPont OEM and PPG CeramiClear clearcoats. The CeramiClear showed better
gloss retention than the control with little color change. Table 3 details the test results.
Please call me should you have questions or comments at (810)750-0040. Thank you for
the opportunity to perform the above work for Nanovere Technologies, Inc.
We look forward to working with you in the future.

DESCRIPTION OF TEST METHODS
Chip Resistance – Per ASTM D3170. This method covers the determination of the resistance of
coatings to chipping damage by stones or other flying objects. One pint of standardized road gravel
(~ ½” diameter) was projected by means of controlled air blast (70 +/- 5 psi) at the panels. One set was
tested under ambient conditions and another set tested at -29oC +/- 2oC. After gravel blast, tape is
applied and removed from the surfaces. The panels are rated using visual standards in the test method.
They are summarized below:

Delta E (ǻE) – Per SAE J1545. This method measures the color of the exposed samples and the color
of the unexposed samples and calculates a color difference (ǻE) by the square root of the sum of the
squares of the delta L*, a* and b* values obtained from the color measurements.
Falling Sand Abrasion – Per ASTM D968 Method A. This method covers the determination of the
resistance of organic coatings to abrasion produced by abrasive sand falling onto coatings applied to a
plane, rigid surface. A specified amount of sand was allowed to fall from a specified height through a
guide tube onto the panels until a minimum of 4mm area of clearcoat was removed. This is the end
point.
Gloss – Per ASTM D523. This method covers the measurement of specular gloss of non-metallic
specimens for glossmeter geometries 20o, 60o and 85o.
Humidity Resistance – Exposure per ASTM D4585. This practice covers basic principles and operating
procedures for testing water resistance of coatings using controlled condensation. A vapor temperature
of 60oC was maintained for the duration of testing. Immediately upon removal from the humidity
chamber, the panels were observed for defects including blisters, blushing, color change, rust, water
spots, etc. If no defects were observed, the panels were rated as PASS.
Impact Resistance – Per ASTM D2794. This method covers a procedure for rapidly deforming by
impact a coating film and its substrate. A standard weight is dropped a distance so as to strike an
indenter that deforms the coating and the substrate. The indentation can be either an intrusion (direct
impact) or extrusion (reverse impact). Films generally fail by cracking. The results are reported as the
maximum number of inch-pounds of force applied to the coating and substrate at which the coating does
not crack (P for pass) or when the coating cracks (F for fail).
STS #306_1C
Scrape Adhesion – Per ASTM D2197. This method covers the determination of the adhesion of organic
coatings when applied to smooth, flat (planar) panel surfaces. The adhesion is determined by pushing
the panels beneath a rounded stylus or loop that is loaded in increasing amounts until the coating is
removed from the substrate surface. Two measurements were recorded, the first the load at which
marring of the surface was observed, and the second the load at which the clearcoat was removed by the
stylus.
Transmission & Haze – Per ASTM D1003. This method covers the evaluation of specific lighttransmitting and wide-angle-light-scattering properties of the planar sections of materials. The
clearcoats were drawn down over glass panels, cured and measured.
Weatherometer Resistance – Exposure per SAE J1960. This method covers the practices and
procedures for the simulated weathering of coated panels.
